IntroductionProgramme SwitchGripsWe understand that as an amputee youwant to be as independent and free aspossible. That’s why we see bebionic3 asenabling technology. A hand that becomespart of who you are, enabling you to get onwith your life.The hand has two operating modes:opposed and non-opposed, with a choiceof grip patterns available in each position.To move the thumb position, simply holdthe base of the thumb and manuallyreposition it.Each finger in the bebionic3 hand movesnaturally so the hand can function like ahuman hand. Controlled in a similar wayto other myo-electric hands, electronicsmeasure changes on the skin coveringthe control muscles, when the musclecontracts it sends a signal to the hand toperform the desired movements.be yourselfThe programme switch on the back of yourhand has two functions:1. Switching your hand ON and OFFOpposedNon-opposedWhether it’s carrying bags, eating meals,tying shoelaces or typing an emailbebionic3 helps you achieve almostanything you need to do.A single press for longer than twoseconds will switch the hand ON. Asingle press for longer than two secondsand less than four seconds will switch thehand OFF.With 14 reliable grips and hand positionsthere is a grip pattern suited to everysituation. From power grip, whichcomfortably holds a glass or shakessomeone’s hand, to mouse grip, whichallows control of a computer mouse,bebionic3 offers a wide and unique varietyof functions.When the hand is first turned on itopens fully, this allows the hand tocalibrate before use. It is very importantnot to stop this process happening.2. Alternating between your primaryand secondary grips.When the hand is switched ON, a singlepress (less than two seconds) will switchbetween your primary and secondary grippatterns. This will be accompanied by ashort bleep and vibration (if activated byyour practitioner).In opposed, the thumb is opposite thefingers, allowing grips like pinch and power.In non-opposed, the thumb is in line withthe fingers of the hand, allowing gripslike key and finger point. The thumb canbe manually moved between these twopositions.The following pages detail a number of thegrips available. If you see grips that you feelwould be of use to you, your practitionercan set these up for you.Please do not attempt to modify yourbebionic3 hand yourself.

Opposed GripsWhere your thumb is in opposition to the fingersSERIOUS WARNINGNEVER use a bebionic hand with firearms.TripodPinchPowerActive IndexTripod allows you to grip objectsbetween the thumb and the indexand middle fingers. It is useful forpicking up, holding and manipulatinga variety of everyday items, such ascar keys, coins, jar lids and pens.Pinch is similar to tripod but usesonly the index finger and thumbto grip. This type of grip is alsouseful for picking up, holding andmanipulating a variety of everydayobjects, such as car keys, coins, jarlids and pens.In power grip all four fingers closetogether to grip around largerobjects such as a ball, a piece offruit, a bottle or home and gardenutensils. The thumb then closesonto the fingers for additional gripsecurity. Power grip also allows youto shake someone’s hand.In active index grip, the hand willgrasp around the handle of anobject, such as a spray bottle, andthen position the index finger overthe lever of the device. The indexfinger is now under independentuser control to operate the trigger.To exit this grip, an open signal willfully open the index finger beforethe other fingers and thumb releasetheir grip of the object.Active index is a unique feature ofbebionic hands and is not availablein other prosthetics hands.

Other GripsFurther functions of your bebionic3 hand.Precision GripsThere are two variations of precision grip: precision open, where the remainingfingers stay fully open, and precision closed where the remaining fingers closefully.Precision is the best grip for picking up and manipulating small objects quicklyand accurately. Initially both the index finger and thumb close, the thumb pausesmidway whilst the index finger continues to close to grip the object. This makesit easier to position the fingers to pick up smaller objects.HookPartially closing the hand in powergrip will create hook grip, which isuseful for carrying a shopping bagor briefcase.Finger AdductionAs the bebionic3 hand closes thefingers move together naturally - thisallows thin objects, such as cutleryor a toothbrush, to be grippedsecurely between the fingers.Adduction grip is most functionalwith the hand in power grip, but itcan also be used with the hand inkey or tripod grips.

Other GripsFurther functions of your bebionic3 hand.be yourselfOpen PalmOpening the hand fully, with thethumb in the non-opposed position,creates a flat palm, ideal for carryinga small bowl or plate.Relaxed HandFor those times when you are notactively using the bebionic3 hand,simply select the relaxed handposition for a natural appearance.

SwitchingGrip PatternsThe first grip pattern available, in eachoperating mode, should be the grip you willuse most frequently. You can then switchto a second grip pattern by applying eithera co-contraction or a double OPEN signalto the hand. It is then possible to switchto a further two grip patterns in each modeby pressing the programme switch on theback of the hand.An additional three grips and positions -hook, finger adduction and open palm -are achieved as part of other grip patterns.This means you will be able to select up to11 grip patterns that will be most beneficialin your day-to-day life.Note: - Your practitioner will work withyou to programme the hand with themost appropriate grip patterns to suit yourlifestyle. They will also work with you to findthe easiest way to change between grips.For certain grip patterns, it is necessaryfor the practitioner to adjust the thumbalignment, so that the contact positionbetween finger(s) and thumb is optimised.For instance, the thumb contacts the indexfinger for precision and pinch, whereas intripod the thumb contacts the index andmiddle finger.UseYour prosthetic provider will help you tobecome proficient in using your bebionic3hand.
